KNOCKDOWN BOX.

Application filed January 26, 1921.

To 4all io/w'm` t may concer/11,:

Be it known that JOHN L. Konan, `a citi- Zen of the United States of America, residing at lauwatosa, in the county of Milwaukee and State of Viisconsin, has invented new and useful Improvements in Knockdown Boxes, of which the following isa specification.

The object of the invention is to provide a simple and inexpensive form of knockdown box or container suitable for use in shipping cheeses and other products from the producer to the market and adapted to be packed and crated in compact form for return to the producer, las a means of economizing containers by repeated re-use a-nd of returning the vcontainers for such re-use within the minimum space and hence at the minimum cost of transportation; and with this object in view the invention consists in the construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein:

Figure 1 is a sectional view of a stack of nested boxes or containers crated for reshipment as empties.

Figure 2 is a similar view taken on the plane indicated by the line 2 2 of Figure 1.

Figure 3 is a plan View showing the crate in section.

Figure t is a detail view of a follower used in connection with the crate.

Figure 5 is a detail sectional view of one of the boxes or containers of a round or cylindrical form.

Figure 6 is a perspective view of one of the box or container elements.

Figure 7 is a similar view of a rectangular form of box element.

The box or container consists essentially of the telescopingelements 10 and 11, respectively representing the body andv the cover adapted to be fitted together as shown in Figure 5 in the manner common to cheese boxes and the like and whereas in said form of box the side wall is cylindrical, it should be understood that the invention is not limited to such form but is applicable equally to boxes of a rectangular form as indicated in Figure 7, whether square or of equal dimensions laterally and longitudinally, or elongated or of oblique form as indicated in Figure 7.

Each of said box elements, namely the body and the cover, either of which may Serial No. 440,025.

be represented by the illustration in Figure 6, owing to the fact that said box and body are of corresponding construction except as to the diametrical dimensions, is diametrically split through the side walls from the free edges to the base represented by the disk 12, the sections 18 of said side walls thus respectively representing one half of the contour of the box or container and adaptedto be spread apart as indicated in Figure 6 upon a diametrical fold line 12a in the diskv forming the base, whether this base represents the bottom of the box or the corresponding member of the cover. This fold line may be formed by bending or doubling the disk or in any preferred or equivalent manner, to the end that the sections of the disk base are adapted to lie in angular relations as shown in Figure 6 and also as indicated in Figure 1, so that the elements of the box may be nested in close relation for ultimate enclosure in a crate such as that illustrated in Figures 1 to 3 inclusive at 14. Preferably the crate is provided in its bottom with a V-shaped form of spreader 15 and also with a follower 16 designed to be super-imposed upon the uppermost box member as shown in Figures 1 and 2, said follower having a V-shaped head 17 and a stem 18 upon the extremity of which the cover 19 of the crate may bear.

The body and cover elements of a plurality of boxes may thus be nested and enclosed within a single sheet in such compact and space economizing relations as to provide for re-shipment or return to the producer at the minimum freight rates and under conditions insuring the safe transportation thereof, and to the end that the elements may be set up and arranged for immediate use upon receipt at the factory or producing point, the sections of the walls of the elements are provided with tapes 20, preferably of iexible and suitably of textile material arranged so as to overlap the adjacent end of the complementalwall sections to which they may be attached either adhesively or otherwise as may be found desirable in practice.

Obviously with reference to boxes designed for the shipment of cheese and like commodities the folding and nesting characteristic of the box as described'adapts it to be forwarded in compact and economical form from the box maker to the pro-.

ducer Who may then set up the elements and imite them to enclose and' protect the product, with a minimum oi eliort and` expenditure of time upon'. the part oitthe Workmen or help.

As above noted the utilization oil' this method of collapsing and nesting is not limited to boxes having` cylindrical si-de Walls but is equally applicable to boxes having a rectangular form such as that in'- olicated in Figure" land which has an ad vantage over the folding' or lniock-dewn pasteboardboxes now in. common use in that tbe joints of the' receptacle when' set up are o'l'Tv very" much more rigid and strain; resisting quality than' is possible to secure' with a Abox'v in which 'folding is eifectedL at the angles between' the elements oi4 the' side Walls and between the side Walls and the' bottoni or disk constituting the base. The only j'ints required in connectionjwith a box' constructed as herein described are' those providedy between the sections ofy the' diametrically split sid'e Walls which. are am# ply` reinforced when the box is set up' by the overlapping tapes which serve as' se.-`

curing, means. In" practice it is also preferable ini lifting. the complemental elements of the container together to dispose4 the joints of the two' elements4 in" different planes and preferably in planes perpendicular tol ea'ch other.

The invention having been described, what isr new and useful is:

1. A collapsible box adapted to be arranged' in nested relation with similar boxes, and con'iprising a bottom and side Walls of WlfiieliI theI liatt/er are' split in the plane of a diametrically fold line in the base, and adapted tobe brought into abutting' reliat'ion at said.v slits, ande flexible textile tapesv arranged to overlap the abutting sections of saidj wall sections andv secured thereto;

2. The coinlni'nationl with a plurality of knock-down boxes liaving bottoms formed: with diametricalzly fold lines andl side Walls split on said fold lines whereby' they' are' adapted "for nestedv relation in cross sectionally\f/sli`apedx form', of a. container provided its bottom4 with an inverted tft-shaped'A spreader" adapted for' the reception of." the bottomro the' lbwve'rmost container", and* pre-Y Videcl at its topA witl'r a foliowverhaving ai V- shapedE headi engaging the' inner surface of tlie bottom4 offt'lie uppermost box, and stemI carrying' sai'd headi'and" depending' from thel top of the crate.

In testimony' whereof he a-'Hifxe'sy his signature; i
